Known Affected Releases

17.2.1

Description (partial)

As part of CSDL requirement the default box config changed from ?transport input all? to transport input ssh.

If a customer is having "transport input all" and reloads from 16.x to 17.2.1 the config will be auto converted to "transport input ssh"
There is no issue with reload.

There is no issue when customer reload the device from 16.x to 17.2.x and then enters ?transport input all? from CLI (In this case transport input all will be effective)

The issue is seen when a customer does config replace with a configuration file from older releases which has default ?transport input all?
In this case the code translates this to "transport input none" instead of "transport input ssh" and all the access will be blocked including telnet.

No workaround for this issue. Only way we can prevent is to edit replace file and add ?transport input ssh? command.

Symptom:
issue is seen when a customer does config replace with a configuration file from older releases which has default ?transport input all?

Conditions:
issue is seen when a customer does config replace with a configuration file from older releases which has default ?transport input all?
